AIMThe purpose of the present study was to investigate the progression risk factors of periodontal disease by individual characteristics at baseline in a Greek adult population.

METHODSThe study sample consisted of 854 individuals. All participants were clinically examined and answered questions regarding sex, smoking status, socioeconomic status, low educational level, frequency of dental follow up, and oral hygiene habits. Serum levels of disease markers were investigated, and attachment levels were clinically recorded. For the assessment of periodontal disease progression, additional clinical attachment loss (CAL) was used if one or more sites showed a 3 mm or more increase in probing attachment level over a 2-year period. Statistical analysis was performed by using a modified multiple Poisson's analysis model.
